> This test currently has several flaws:
> - It calls DN.updateBlock with a BlockInfo instance, which then causes
> java.lang.RuntimeException: java.lang.NoSuchMethodException:
> org.apache.hadoop.hdfs.server.namenode.BlocksMap$BlockInfo.<init>() in the
> logs when the DN tries to send blockReceived for the block
> - It assumes that getBlockLocations returns an up-to-date length block after
> a sync, which is false. It happens to work because it calls getBlockLocations
> directly on the NN, and thus gets a direct reference to the block in the
> blockmap, which later gets updated
> This patch fixes this test to use the AppendTestUtil functions to intiiate
> recovery, and generally pass more reliably.
